MEAT-CUTTING MACHINE.

Specification of Letters Patent.

Patent-ed Aug. 1, 1916.

pplication filed August 14, 1915. Serial No. 45,546.

at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Meat-Cutting Machines; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to'make and 1 use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful machines for cutting porterhouse and sirloin steaks from beef loins and consists in the provision of an adjustable table adapted to support the beef loin and so arranged as to be swimg horizontally or tilted at angles to a vertical plane in order to bring the loin in proper position-for cutting steaks from either the porterhouse end or sirloin end of a beef loin, continuously or alternately as desired, with a revoluble cutting saw.

It is well understood by butchers that beef loins vary greatly in dissimilarityof shapes and sizes, some being large, others small, some more or less fatty, lean, rawboned, thin, blocky, etc., and having reverse sides, right and left, and it is also well known that various butchers operate in different ways in cutting the loin from the side of the beef.

It is the purpose of the present invention to provide means whereby the steaks may be cut uniformly from loins of various sizes and shapes.

The invention consists of a simple and efficient mechanism of this nature having various details of construction, combina-- tions and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure l is a top plan view of the loin steaking machine. Fig. 2 is a vertical central sectional view through the machine, parts being shown in elevation. Fig. 3 is 'a sectional view on line 3 3 of Fig. 2, looking in the direction of the arrow. Fig. l is an enlargeddetail view. partly in secti ni1nd elevation, showing the loin carrying car.-

.sition.

riage adjusted to different tilted positions, and Figs. 5, 6 and 7 are diagrammatic views showing different positions in which the loin of beef is'positioned when cut.

Reference now being had-to the details of the drawings by numeral, 1 designates a table upon which a frame 2 is mounted, and 3 designates a motor mounted upon the block 4: upon the table and adapted to afford power for driving the apparatus. Said frame has standards 5 upon which the shaft 6 is journaled, having a pulley 9 journaled thereon, and a shaft 7 is mounted upon the carriage and has a pulley 1O thereon. A movable saw carriage, designated by numeral 12, shown clearly in Fig. 1 of the drawings, is provided with slots 13 upon lts opposite edges adapted to receive the gulde flanges 14: which project from the inner marginaledges of the plates 15, and

-a handle 16 upon said carriage affords means for moving the same longitudinally forward, while a spring 17, fastened at one end 18 upon the carriage and the other end to astationary pin 19, serves as a means for returning the carriage to its starting 130- A shaft 20 is journaled in suitable bearings upon the saw carriage and has a circular saw 21 fixed thereto. A cable or belt 22 passes about a pulley 23 fixed to the driving shaft of the motor shaft 24 of the motor 3, thence about the pulleys f), 27, 10 and 25, which latter is journaled upon a shaft :26 of the frame. Said cable or belt also passes about a pulley 11 which is fiXed to the shaft 8. i

Mounted upon the block or standard 28 upon-the table 1 is a swiveled post 29,-the lower end of which has a concaved bearing surface adapted to rest upon the ball bearing 30, which is seated in a semi-spherical raceway 31 in the bottom of the recess 32. Said post has a contracted extension 33 at its upper end which is apertured, and 34 is a swinging frame adapted to support a movable ta'ble mounted thereon. Said frame 34 has a bracket member 36 which is forked and fits over the contracted upper end 38' of the post 29 and has apertures which are adapted to register with an aperture in said projection 33, one of the apertures in said bracket member being internally threaded to receive the threaded end'of the shaft 37. It will be noted upon reference to Fig. 2 of the drawings that the post 29 is mounted gas in an adjustedposition. A minutely fluted eccentrically upon the block 28 and that the bracket member 36, which is pivotally connected to'said post, is also mounted eccentrically upon the frame 34, so provided that said frame 34 will be' allowed to swing properly to bring the loin mounted upon the table supported by- 1 said frame into proper position to be cut when the table is adjusted to different positions relative to the revoluble saw. An anti-friction roller 38 isjournaled upon the shaft 37 and is adapted to rotate upon the upper surface of the block 28, while said shaft passes through the registering apertures in the upper contracted end of the post-29 and the apertures in said yoke 36, a jam nut 39 .upon the shaft being adapted to bear against'the yoke. A hand wheel 40 is fixed to the'shaft 37 and forms a means whereby the shaft, connected as shown clearly in Fig. 1 of the drawings, may be turned and with it the frame 34. The outer end of said shaft. 37, it willbenoted, is journaled in an apertured extension 41 of .the. frame 34. Said table 35 has a boxing 42 projecting -from the lower under surface thereof which 45 mounted? .h asan elongated slot 43, and 44 is a bolt passing throughsaid slotand also through an ,aperture the frame 34 and has a'nut it h' aded end. By the in'iounted as shown provision ofi and described, nieans is afi'orded whereby V "the table may have a longitudinal movementin opposite directions and, by tightening the nut upon the bolt, the table may be held or corrugated runwayor track, designated bynumeral 46, is mounted upon the frame 34, the flutings or serrations 47 upon its up- '40-- per edge being shown clearly in Fig. 4 of the drawings. p

48. designates a resilientpawl fastened to the under surface of the table 35 and adapted to engage the serrations of the track to hold tlie'table in a set longitudinal position while each steak from the loin held thereon is being cut. Said table has flanges 49 rising therefron with a space 50 at their inner ends and through which the meat cutting saw passes as the saw is moved over the table. A bracket-shaped block5l is provided with pins 52 which project from the under surface thereof and is designed to engage holes, not shown, formed in the table 35, said block being utilized when the piece of'meat to be cut, designated by numeral 53, is of small size and inconvenient to cut v grain of the meat.

tion rollers 54 mounted in recesses 55 formed in the upper ends of the standards 56, as shown clearly in Fig. 2 of the drawings and upon which the table 35 rests.

In operation, power is applied to the apparatus through the motor 3 and the shaft and saw given a continuous rotary movement. The loin to be cut is held upon the table 35, the table first being adjusted in different relative positions, in conformity with the condition of the loin to be steaked, as shown in Figs. 1 or '4 of the drawings, accordingly as may be necessary to cause the saw---to cut at the rightangle to the grain of the meat. By pulling forward upon the handle 16, the saw carriage and saw may be moved forward so that the saw will assume the position shown in dotted lines, it being understood that the saw is constantly rotating in its different adjusted positions. The loin is held upon; the table and, when a steak has been severed the table 35 may be moved forward one or more serrations 47, the va rious notches serving to gage the thickness of the slices. lVhen the pressure is relieved from the handle 16,;the coiled spring 17 will return the saw carriage and saw to their normal positions, shown in solid lines in Fig.

2.0f the drawings. It will'be understood" that theloin of beef may be so positioned .upon the table that the steaks may becut either from one end or by reversing the loin out upon the opposite end or from any part thereof.

Upon reference to Fig. l of the drawings, it will be noted that the carriage is shown indifferent horizontal adjusted positions relative tothe cutting plane of the saw, while in Fig. 4 of the drawings the table holding the meat is shownas being capable of being tilted to different inclined positions in order to bring the surface of the meat to be cut in proper position, it frequently jheing the case that the ends of'the loin parts of beef are cut at different angles to thefdengths thereof a nd, by the adjustable table, the ends may be brought so-th'at. the steaks will be cut at right angles to the It will also be noted that, by the turning of the shaft 37 in one direction, the jam nut and the thread will release the table to allow the same to be able transversely. of the frame and table to,
